SWING-STANCI-IION.

To all whom it may concern:

Be it known that I, RICHARD LOGAN, a citizen of the United States,residing at Lisbon, in the county of St. Lawrence and State of New York,have invented certain new and useful Improvements in Swing- Stanchions,of which the following is a specification.

This invention relates to care of live stock and has especial referenceto a novel formation of stanchion to be employed for securing cattlewithin their stalls.

An object of this invention is to construct a stanchion which is adaptedfor pivotal movement in order to form a device of this character whichwill be as comfortable as is consistent with the nature thereof.

The invention has for another aim the provision of a stanchion withmeans where by the same will be locked or released from a distancerearwardly of the same, thereby producing a device which .is applicableto congested conditions.

The invention further aims the provision of a stanchion, the arms ofwhich are provided with means whereby the same are retained fromrotation when in an open position for the reception of the head of thecattle therebetween.

For a full understanding of the invention reference is to be had to thefollowing description and accompanying drawings, in which.

Figure 1 is a front elevation of the complete device in an openposition. Fig. 2 is a view of the same showing the same as closed. Fig.3 is a rear elevation of the stanchion showing the bars in an openposition. Fig. 1- is a section on the line l 1 of Fig. 3. Fig. 5 is atransverse section of the device on the line 5-5 of Fig. 3.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

Referring to the drawings, the numeral designates a rectangularframework which is vertically disposed and which is provided with araised base 11 intermediate of the lower portion thereof. A cross-arm 12is pivotally mounted upon the base 11 by means of a bolt 13 which issecured vertically therethrough and which is extended through the base11 into the lower portion of the framework 10. A washer 11 is rigidlypositioned about the bolt 13, the

bolt 13 being rigidly secured to the crossarm 12, and is secured at oneside to the inner extremity of a spring 15 which is carried by the base11 and which exerts a tension upon the washer 1% to normally retain thecross-arm 12 in the plane of the framework 10. The opposite extremitiesof the cross-arm 12 are forked in which are pivotally secured the lowerextremities of bars 1 of the bars 16 and 16 when pressure is ex crtedagainst the same. Swivelly mounted upon a king-bolt 18 is a head 19which is dependedcentrally upon the upper portion of the framework 10intermediate of the upper extremities of the bars 16 and 16 which areprovided at their lower ends with beams 20 and 21 which are disposed inparallel and extend longitudinally within the frame 10. The beams 20 and21 are provided between their outer opposite extremities with arms 22and which depend therefrom and carry idlers 21 and 25 over which ispassed an endless belt 26. The endless belt 26 is rigidly secured at itsopposite portions to the bars 16 and 16 for the purpose of insuring auniform movementof the same relative to one another when operated. Thebar 16 is provided adjacent its upper extremity with an eye-bolt 27which carries the inner extremity of a spring 28 disposed upon an car 29which is upwardly extended from the outer adjacent end of the crossbeams20 and 21. The head 19 is provided upon its outer face with a pulley 30which is adapted for the reception of a cable 31 which is secured at itslower extremity in the eye-bolt 27 and which extends upwardly from thehead 19 where it is engaged over a series of pulleys 32 and depended ata convenient point where it is provided with a handle 33 for engagementby the operator. The opposite side of the head 19 is provided with anLplate 31 which is hingedly disposed between lugs 35 ouhvardly extendedfrom the head 19, the flanged portion of the plate 3 1 being extendedoutwardly and en gaged with the lower extremity of a cable 36 which ispassed upwardly therefrom through a guide 37 where it is engagedover aseries of pulleys 38 to a position adjacent the cable 31 where it is'provided with a handle 39. The plate 34 is provided with latches 40 and41 which are oppositely disposed therefrom and adjustably securedthereto by means of the formation of a plurality of apertureslongitudinally disposed in the same through which detachable pins 42 aresecured and which are supported in such relation by means of slottedflanges 43 which are turned outwardly and vertically from the head 19.The plate 34 is adapted to be tensionally retained against the face ofthe head 19 by means of coil springs 44 which are positioned loosely inenlarged apertures formed through the head 19 and are secured at theiropposite extremities to the inner face of the plate 34 and to atransverse pin positioned against the op posite face of the head 19. Thelatches 40 and 41 are each provided with inwardly beveled extremitieswhich are adapted for sliding movement over beveled faces of the bars 16and 16 for the purpose of admitting of the automatic action of thelatches 40 and 41.

The operation of the device is as follows :N0rmally the bars 16 and 16are converged and engaged against the inner recessed faces of theabutments 17. he stanchion is adapted to be mounted at the end of astall and the cattle which is to be secured therein is driven into thestall and is adapted to engage its head between the bars 16 and 16 whenthe operator grasps the handle 33 to draw upon the cable 31 to swing thebar 16 inwardly. This action causes the movement of the endless belt 26as the same is secured to the bar 16 and thus causes the inward movementof the bar 16 owing to the rigid connection between the same and thebelt 26. As the bars 16 and 16 are drawn inwardly the same engageagainst the outer extremities of the latches 40 and 41 and ride over thebeveled ends formed thereon to swing the plate 34 outwardly and to admitof the passage of the bars 16 and 16 inwardly of the shoulders ofv thelatches 40 and 41. lVhen the bars 16 and 16 are closed the shoulders ofthe latches 40 and 41 are engaged with the bars and are pressedoutwardly of the same when they are admitted to swing inwardly by theaction of the springs 44 on the plate 34 to prevent the divergence ofthe bars 16 and 16 and to thus secure the same in a locked position.

lVhen it is desired to release the cattle from the bars 16 and 16 theopposite handle 39 is grasped and drawn downwardly which causes theraising of the flanged portion of the plate 34 through the medium of thecable to swing the latches 40 and 41 outwardly bolts 13 and 1S and admitof the side motions of the cattle which are secured therein. The spring15 is employed for the purpose of holding the bars 16 and 16 in theplane of the frame 10 when the device is in an inoperative position inorder to maintain the same in such position that it needs no adjustmentto drive a herd of cattle therein.
